Today: Indiana Dunes National Park Ranger Rafi Wilkinson is on "Regionally Speaking" to talk about the always-changing Mount Baldy. (Pictured: a "Smithsonian Magazine" illustration of the sand dune seven years ago, when a boy was pulled into a sinkhole in the dune. He was rescued with only minor injuries.) He says Mount Baldy has already taken over parking spaces and access roads at the park. Travis Tester, the Chief Development Officer for Indianapolis-based "Foster Success" and former foster youth Rimy Morris talk about the organization's "Friends Giving" campaign. Rimy -- a Gary native -- talks about what the holiday season is like for foster youth. And Side Effects Public Media reporter Darian Benson has a report on how public libraries are helping communities navigate the challenges of some of their patrons, by hiring social workers.
